  • Abstract
    We describe a novel method of velocity control that addresses the measurement requirements of the watt balance projects. The method is based on the use of both a heterodyne Michelson´s interferometer and a home-made high frequency phase shifting electronic circuit. Results show that intrinsic relative uncertainty of 10-9 on velocity can be reached with this method over a translation range of 80 mm
